FAQs
1. What is the most important part of a budget?
The most important part of any budget is revenue forecasting, because it sets the limit for what you can spend and save. Without a realistic estimate of your income, it’s impossible to plan effectively. Forecasted revenue drives every other decision in your budget, from how much you can allocate to fixed expenses, to how much you can save or invest. A good budget always begins with a clear picture of expected earnings.
2. How often should I review my budget?
Budgets should be reviewed at least once a month to stay aligned with your financial goals. If your income is irregular or you’re going through a period of major change, more frequent reviews can help. Regular reviews allow you to spot overspending early, adjust for unexpected costs, and make sure your savings goals are still on track. It keeps your budget dynamic and responsive.
3. Should I include savings in my budget?
Yes, always include savings in your budget, just like you would with rent or bills. Treating savings as a fixed monthly expense helps you build discipline and ensures you’re consistently putting money aside for emergencies, big goals, or future investments. Without allocating for savings in your budget, it’s easy to spend what’s left over and fall short on long-term financial targets.
4. What’s the difference between fixed and variable expenses?
Fixed expenses are consistent and predictable costs you pay regularly, like rent or insurance. Variable expenses fluctuate depending on activity or usage, such as utility bills, groceries, or fuel. Understanding the difference helps you identify which costs you can control more easily. It also improves your ability to adapt your budget when needed, as variable expenses offer more flexibility.
5. How do I start budgeting if I have irregular income?
If your income varies from month to month, start by basing your budget on your lowest recent monthly income. This approach helps ensure you can always cover essentials, even in lean months. Then, when you earn more, you can allocate the extra funds toward savings, debt, or discretionary spending. Prioritise essentials, build a buffer, and adjust your budget monthly to reflect actual income.
